The aim of this study was to detect changes in the profiles of metabolites induced by the administration of cyanidin 3-glucoside to adult male rats. This metabolomic approach made it possible to identify as many as 8 metabolite markers, including bile acids, reduced and oxidised glutathione and some lipids. Such changes suggest that cyanidin 3-glucoside has a major effect on tissue antioxidant status as well as on energy and glucose metabolism.

Pesticide residues on grapes and in vinification process of two white and two red grapevine varieties were monitored. Crushed grapes, cake, must, lees and wine were sampled during the vinification process. Additionally, grapes were sampled during the ripening process. Boscalid and phosalone were the most persistent pesticides in grapes during ripening. The concentrations of pesticide residues in must and wine were significantly diminished through separations of the solid and liquid phases during the vinification process, particularly the pressing of crushed grapes and wine racking after alcoholic fermentation.

Pectate lyases are major parasitism factors in plant parasitic nematodes. We have analysed polymorphisms of pectate lyase 2 (pel-2) gene, which degrades the unesterified polygalacturonate (pectate) of the host cell-wall, in the genus Globodera. The results showed that pel-2 genes polymorphism may be implicated in the adaptation of Globodera species to different host plants.

In the experiments honey bee (Apis mellifera) larvae were exposed to one of nine pesticides and/or were challenged with the parasitic mite, Varroa destructor. Gene-expression changes in larvae were measured using quantitative PCR (qPCR) targeting transcripts for pathogens and genes involved in physiological processes, bee health, immunity, and/or xenobiotic detoxification. We discovered that Varroa-parasitized brood resulted in significantly higher transcript abundances for the antimicrobial peptides abaecin, hymenoptaecin, and defensin1. Transcript levels for Prophenoloxidase-activating enzyme (PPOact), an immune end product, were elevated in larvae treated with myclobutanil and chlorothalonil (both are fungicides)(P(0.001). Transcript levels for Hexameric storage protein (Hsp70) were significantly upregulated in imidacloprid, fluvalinate, coumaphos, myclobutanil, and amitraz treated larvae. We demonstrated definitive impacts of pesticides and Varroa parasitism on honey bee larval gene expression.

Ethylene evolution and expression of ethylene related genes were observed on apple fruitlets after application of plant growth regulators or shading treatment. Shading and plant growth regulators influenced expression of ethylene related genes and ethylene evolution. However, the expression of observed genes was not closely related to total fruitlet abscission, but have strong effect on abscission dynamics.
